BRUSH-CUTTING ATTACHMENT FOR MOWINCr-IVIACI-IINES.

To all whom it may concern:

Ile it known that I, JULIUS CHARLES STE- vnxs, of Didsbury, in theProvince of Alberta, Canada, have invented new and useful Improvementsin Brush-Cuttin Attachments for Mowing-Machines, of which the followingis a specification.

My invention relates to improvements in ln'ush-cutting attachments formowing-machines more particularly for use in connection with removingthe heavy brush covering the ground in western Canada, and the object ofmy invention is to dispense with the set of knives and guards now usedin the ordinary grass-mowers and brush-cutters; and

to provide a simple, cheap, but most effective and strong apparatus forthe purpose before set forth, and my invention consists of the partshereinafter particularly described and pointed out in the claims formingpart of this specification.

Figure 1 is a plan-view of an ordinary mowing-machine with my knifeattached thereto, and Fig. 2, is an enlarged crosssection on the lineaZ), Fig. 1.

In the drawings, like characters of reference indicate correspondingparts in each figure.

Although I show and describe my invention as being used in connectionwith the ordinary mower-machines (with the cutterbar and its kniferemoved) it will be understood that I do not confine myself to using myinvention in connection with any particular construction ofmower-machine.

A is a non-reciprocating knife or blade which is held approximately atthe angle shown to the line of draft which is approximately 40 degrees,so that, as the vehicle is drawn, it will be moved over the ground andsever the stocks of the brush. The front end B is suitably secured tothe shoe C.

I) is the front frame of the mower-frame E, and F are brace rods. Thetongue G is extended beyond the back of the machine by means of anextension I-I bolted, or otherwise secured thereto, as shown at h.

I is a brace secured at 2' to the knife A. It will be noticed that thebrace I passes behind its adjacent wheel of the mower machine, so thatthe knife A may be swung around its hinged connections without anyhindrance.

2 is a U-shaped bracket supported on the extension II.

3 is a coupling secured to the brace I and Specification of LettersPatent.

pivoted to the bracket 3 by means of its pierced head f.

It will of course be understood that the shoe 0 is pivoted to themowing-machine frame: therefore wherever desired, the knife or blade Amay be raised and lowered on the pivoted point of the shoe C, and on thebracket 2, by means of the brace I. The knife or blade A. will bepreferably mounted so that its front end will be in at. *ance of thewheels G is a scat-post, and T is a foot-rest secured to the brace I,and is placed in convenient relationship to the seat (not shown) carriedon the seat-post (3. By means of the said foot-rest the driver can keepthe rear portion of the knife or blade A as close to the ground asdesired.

The ordinary lever and connection for raising and lowering the usualcutter-bar, have not been shown in the drawings, as the illustration ofthe same is not essential to a full comprehension of this invention:but. it will be understood that the said lever and connection may beused to raise and lower the knife or blade A.

8 is a strengthenii'ig-strip preferably made of wood, suitably attachedto the underside of the knife or blade A. Upon referring to Fig. 9 itwill be noticed that the strengthening strip 8 is so placed as not; tointerfere with the cutting-edge 9 of the knife or blade A.

10 is a wing or guard secured by suitable brackets 11 to the knife orblade A. This wing or guard projects above the knife or blade A at asuitable angle.

The knife or blade A will be made of very fine steel so that it. willtake and keep a very fine edge. As the knife or blade A is essentiallymoved in an angular position to the line of draft, it will be understoodthat it occupies the most advantageous position for the severing of thebrush from its stock.

I find that the most advantagemis angle at which the knife or blade A.operates, is an angle of about d0 degrees, although it will beunderstood that the angle may be somewhat altered at which the knifeoperates. The knife or blade A must essentially be placed so that itsfront end will always be cutting far in advance of the rear or back endof the knife or blade.

What. I claim as my invention is:

1. The combination with a mower-machine-frame; the wheels mountedtherein; the tongue, and the shoe hinged to said lltl frame in advanceof one of the said Wheels; of a nonreciprocating knife secured at itsfront end to the said shoe and held at an angle to the line of draft ofthe mower-ma chine; a support extending fro-1n the back of the saidframe; a brace secured to said knife and resting behind one of the saidWheels, and a bracket carried by the said support to which said brace ishinged as and for the purpose specified.

2. The combination With a mower-inachine-frame; the Wheels mountedtherein; the tongue, and the shoe hinged to said frame in advance of oneof the said Wheels; of a non-reciprocating knife secured at its frontend to the said shoe and held at an angle to the line of draft of themower-ma chine; a support extending from the back of the said frame; abrace secured to said knife and resting behind one of the said Wheels; abracket carried by the said support to Which said brace is hinged, and aWing carried by said knife and situated between the said shoe and thesaid brace, as and for the purpose specified.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing Witnesses.

JULIUS CHARLES STEVENS.
